Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides due to its halogen and aldehyde functional groups that allow for further chemical modifications. Its structure supports the creation of more complex molecules with enhanced biological activity. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build biaryl systems in active ingredients. Also utilized in the preparation of fluorinated organic compounds where the fluorine atom contributes to improved metabolic stability and lipophilicity in target molecules.
